Abstract This study examined the effect of Zeolite soil amendment on performance (growth and yield) sweet corn.The experiment was carried out in rice fields KP. Mojosari, Mojosari District, Mojokerto Regency MK II 2021 (April to September 2021), with 10 fertilization treatments which are combination best improver dose corn plants, including treatment A (control), B (Urea 200 kg/ha, ZA 100 NPK 2...

The renal handling of urea has been studied by many investigators on a host of animals. It has been found that urea is actively secreted by certain species (Munro, '53; Forster, '54), reabsorbed by others (Smith, '31a, b), and in some the renal handling seems to be entirely passive (Shannen, '36). The aglomerular goose fish (Lophius piscatorius) is reportedly able to secrete urea actively from ...

Urea synthesized commercially and formed naturally as a by-product of cellular metabolism is an important source of nitrogen (N) for primary producers in aquatic ecosystems. Although urea is usually present at ambient concentrations below 1 μM-N, it can contribute 50% or more of the total N used by planktonic communities. Urea may be produced intracellularly via purine catabolism and/or the ure...

Urea production rate (Ra) is commonly measured using a primed continuous tracer urea infusion, but the accuracy of this method has not been clearly established in humans. We used intravenous infusions of unlabeled urea to assess the accuracy of this technique in normal, postabsorptive men under the following four different conditions: 1) tracer [13C]urea was infused under basal conditions for 1...

Physiol. 2 1 a(6) : 1524-1532. 1970.-In rats overloaded with urea, at plasma concentrations of 60-80 mM, the proximal fractional reabsorption of urea was not impaired, whereas the cortical tissue-to-plasma urea concentration rati...

Farmer in different parts of Ethiopia uses a similar type fertilizer and amounts that are below the crop requirements, even low soil fertility which limits production general. To solve over-blanket application over agroecology Ethiopian Soil Information System (EthioSIS) mapped recommended types for specific location. A NPSB where Beko village, but rate this was not studied so far. So, field ex...

Urea degradation was measured during 16 experiments in 13 chronic uremic patients being treated with essential amino acids or their analogues. [(14)C]Urea was injected i.v. and the clearance of labeled urea from its volume of distribution was compared with the simultaneous renal clearance of ordinary urea, which averaged 2.0 liters/day. The difference, extrarenal clearance of urea, averaged 3.1...

to evaluate the effects of plant growth promoting rhizobacteria (pgpr) such as azotobacter chroococcum, azospirillum lipoferom and brasilence and pseudomonas fluorescens and nitrogen fertilizer from urea source on yield and yield components of maize (zea mays l.) double cross hybrids (dc 370), a field experiment was carried out in a factorial experiment (5*3) in rcbd with 4 replications. bacter...
